摘要:
Systems and methods for controlling access to a Restricted Area (“RA”). The methods involve: determining whether a person desires to enter RA; checking whether the person is authorized to enter RA using a first unique identifier associated with a wearable access sensor being worn thereby; causing the person's Portable Communication Device (“PCD”) to transmit a second unique identifier and location information useful in determining the PCD's location within a surrounding environment, when a determination is made that the person is authorized to enter RA; using the second unique identifier and location information to confirm that the person is currently located at an access point of RA; and causing actuation of a mechanical actuator to enable the person's entrance into RA when it is determined that the person desires to enter RA, the person is authorized to enter RA, and the person is currently located at the access point of RA.

摘要:
Systems (100) and methods (400) for powering an electrical load (322) in an environment. The methods involve using a battery (310) to simultaneously supply electrical energy to control electronics (308, 316) and a Super Capacitor (“SC”) storage element (314) immediately after a system has been disposed in the environment and turned on. In effect, the control electronics are caused to perform intended functions thereof nearly instantaneously after turning on the system. The SC storage element is charged from a first charge state in which approximately zero volts exist across terminals thereof to a second charge state in which greater than zero volts exists across the terminals. The SC storage element is then used to supply electrical energy to the electrical load of the system so as to cause the electrical load to perform intended functions thereof.
摘要:
Systems and methods for detecting an opening and closing of an object, such as a door or window. The methods comprise: causing a piezoelectric transducer to oscillate in response to an opening of the object; harvesting energy generated as a result of the piezoelectric transducer's oscillation to power a transceiver; and transmitting, from the transceiver to a remote device, information indicating that the opening of the object has been detected by a wireless sensor coupled to the object. The information may specify a logical address linked to a physical location of the object (e.g., a MAC address).

A method for operating a Wearable Access Sensor (“WAS”). The methods comprise: capturing RF energy by the WAS, where the RF energy is emitted within a surrounding environment from equipment disposed at an access point of a restricted area; passing the RF energy through a switch that is normally in a position which provides an electrical connection between an antenna of the WAS and a full wave rectifier of the WAS; performing operations by the WAS to convert the RF energy into direct current for generating electric power; supplying the electric power to an energy storage device of the WAS for charging the energy storage device to a pre-determined voltage level; and supplying power from the energy storage device to a controller of the WAS when a voltage level of the energy storage device is equal to or greater than the pre-determined voltage level.

Systems (100) and methods (300, 400) for controlling access to a restricted area. The methods involve: determining whether a person desires to enter or exit the restricted area based on (1) Received Signal Strength Indicator (“RSSI”) measurement data specifying a power present in a signal received from a Wearable Access Sensor (“WAS”) worn by the person or (2) rate of change data specifying a rate of change of a charging voltage of an energy storage device disposed within the WAS; and causing actuation of a mechanical actuator to enable the person's entrance into or exit from the restricted area when a determination is made that the person desires to enter or exit the restricted area.

Systems and methods for controlling at least one security device based on the behavior of at least one tag. The methods comprise: generating sensor data relating to movement by at least one sensor disposed in a first tag; analyzing the sensor data to determine if an item to which the first tag is coupled is being handled in an unusual, abnormal or nervous manner; determining if an enterprise system has lost communicative contact with the first tag coupled to the item that is being handled in an unusual, abnormal or nervous manner; and causing an operational state of the security device to change in response to the loss of the communicative contact between the enterprise system and the first tag.
